G-Pen Herbal Vaporizer Review


The G-Pen is a small herbal vaporizer from Grenco Science. It is cheap and easy to use. This is a perfect device for anyone who is trying to make the transition smoking to vaping. It has some basic features such as temperature control. This vaporizer will give you smooth, flavorful hits.

The G-Pen was one of the first vaping devices from Grenco Science. There are two versions of the G-Pen; one can be used to vape dry herb while the other one is for concentrate. In this review, we will be looking at the G-Pen herbal vaporizer. Grenco Science released a limited edition version of this vaporizer in collaboration with Snoop Dogg. The Snoop Dogg G-Pen had the same basic features as the G-Pen herbal vaporizer. However, the map of the Long Beach is engraved on the device.

The G-Pen herbal vaporizer is made of stainless steel, glass, and plastic. It is shaped like a pen and is about the size of a marker. You can throw the device in your pocket without any bulkiness. The heating chamber is made of glass, and the mouthpiece is made of plastic. The rest of the device is made of stainless steel. It feels nice in the hand. You can easily use it to vape discreetly in public. The G-Pen is very durable. It will not get damaged if it falls from your hand.

This Grenco Science vaporizer has a 900 mAh battery that is non-removable. This is a standard battery for a device of this size. The battery life of the G-Pen can last you for up to 2 hours or more depending on how frequent you use the device. The package includes a USB charger and an AC adapter for charging the vaporizer. You need to detach the battery from this device to charge it, so it goes without saying that the G-Pen does not support pass-through. Like many vaporizers on the market, you need to press the power button on this device rapidly five times to turn it on/off. When the device comes on, a blue light will flash at its base. You will also see a blue light around the power button. This vaporizer is designed to automatically shut down after about 11 seconds. This goes a long way to save the battery life.

The G-Pen has a small heating chamber. It can only hold a small amount of herb at a time. The device comes with tools for cleaning and loading the chamber. Do not stuff the chamber too tight. If you find the airflow too tight, try stirring the herb in the heating chamber. At the bottom of the chamber is a ceramic plate with a metal coil. The device heats up very quickly. The tank section of this device is replaceable.

The G-Pen supports variable temperature. You can change the temperature of the device by pressing the power button for a few seconds. The LED light around the button will light up when the temperature changes. You can tell the temperature based on the color of the light; a red light indicates 120 degrees Celsius, green is 193 degrees Celsius, and blue is 215 degrees Celsius. After you choose your desired temperature, you need to press the power button to preheat the device. A red light will show while it is preheating. The light will change to green to indicate that you can start vaping. You need to press the power button while taking a puff.

One of the main complaints about the G-Pen has been that it does not only vaporize herb but also does some combustion. You can tell that it burns your herb because it has a smell. You can cut down the combustion of the herb by spacing out your hits. Also, avoid vaping at high temperatures for a long time.

The G-Pen herbal vaporizer can be bought from virtually any top vape store. The device is usually priced at about $70, but you can get it on Ejuice Pack for only $60.16. It comes with several accessories including cleaning tools, a cleaning brush, extra glass sleeves for the heating chamber, and a user manual. This vaporizer comes with a one-year warranty.
